Which of the following statements correctly describes the difference between a Chaitya and a stupa?
The correct option is A. Chaitya is a religious term, while stupa is an architectural term for a mound containing a relic of the Buddha and later on of leading Buddhist saints.
Stupas were built of stones or bricks to commemorate important events or mark important places associated with Buddhism or to house important relics of Buddha. Ashok Maurya who laid the foundation of this group of monuments is said to have built 84,000 stupas, most of which have perished. The best examples of stupas are those constructed at Amaravati, Sanchi, Barhut and Gaya. "One of the most striking architectural remains of ancient India" and the earliest and largest of the three stupas found in Sanchi was built by Ashoka (273-236 B.C.)
Chaitya grihas or halls of worship were built all over the country either of brick or excavated from rocks. Ruins of a large number of structural Buddhist chaity grihas are found in the eastern districts of Andhra Pradesh, in valleys, near rivers and lakes. The ruins located in the districts of Srikakulam at Salihundam, of Visahkapatnam at Kotturu, of West Godavari at Guntapalli, of Krishna at Vijayawada, of Guntur at Nagajunakonda and Amaravati belong to the 3rd century BC and later. The largest brick chaitya hall was excavated at Guntapalli
